Referring to FIGS. 7A and 7B, there are shown that Monascus fermented products affecting lipolysis activity respectively in perirenal and epididymal adipose tissues of male Wister rats fed with high-fat diet. These results demonstrate that lipolysis activity in perirenal and epididymal adipose tissues can be enhanced significantly by feeding the rats with red mold rice (RL and RH). In perirenal adipose tissue, lipolysis activity in RL and RH groups are increased by 12.3% and 17.3% respectively; in epididymal adipose tissue, lipolysis activity in RL and RH groups are increased by 29.0% and 30.0% respectively. Lipolysis activity in epididymal adipose tissue of rats fed with high dosage of red mold dioscorea (DH) is increased significantly by 29.0%. Additionally, lipolysis activity in normal diet group (C) is lower than that in high-fat diet group (HF) because that lipolysis activity is in direct ratio with the amount of body fat under normal circumstance. The more body fat, the more vigorous the metabolism activity in tissue is, and this situation can satisfy the balance of metabolism.

From the above cell and animal experiments, the results reveal that the Monascus fermented products of the present invention can improve the body fat accumulation caused by high-fat diet and stimulate the lipolysis activity in cells. Thus, Monascus fermented products have potential to be antiobesity functional foods.
